Title: Self oscillating drive circuit for an electrodeless discharge lamp
Inventor: GREEN IAN MACDONALD
IPC: H02M7/5383
Filed: 1995-09-18
Abstract: An electrodeless lamp drive coil 16 and a capacitor 14 form a series resonant circuit which is connected to an output node 10 between series connected FETs 4,6, the current in the drive coil 16 being sensed by a feedback capacitor 34 connected via a feedback resistor 32 to the gate of one of the FETs 4,6 so that the circuit is self oscillating at a frequency (eg. 2.8MHz) determined by the series resonant circuit 14,16. The relative positions of capacitors 14,34 may be interchanged, and the capacitor of the series resonant circuit may alternatively be formed by two equal value capacitors (14 a ,14 b , Fig.3) connected between one end of the coil 16 and respective rails of a DC supply. The FETs 4,6 may both be n-type with gates coupled by close coupled windings 28,30 on a transformer TX so that the FETs 4,6 turn on alternately. The two FETs 4,6 may alternatively be of opposite conductivity types (Fig.4), with their gates connected directly to one another and to one end of the feedback resistor 32, thereby forming a self starting circuit in which both the transformer TX and a starting circuit 18,20,22 are eliminated; such a circuit may be very compact and manufactured using surface mount technology as it has no magnetic components, other than the drive coil 16.

Title: Video/graphics memory system
Inventor: YASSAIE HOSSEIN
IPC: H04N5/45
Filed: 1992-11-23
Abstract: A video/graphics memory system includes a memory device (30) having a memory core (14) and first and serial registers (16, 36). The memory device thus has a random-access port (24) for graphics data, a first serial access port (22) for image output to a display, and an auxiliary or second serial port (32) for input and output of video signal data. A single memory thus stores both video and graphics data, while the processor still has access to the random access port of the memory. Two video outputs can be provided simultaneously, or the data withdrawn through the auxiliary port can be subject to processing and then written back into the memory. The memory core has a mask plane. A mask memory is provided, associated with the auxiliary serial port, for exchanging mask data with the mask plane of the memory core, to selectively control the overwriting of data in the memory core. Incorrect use of mask data in the mask memory when the corresponding data in the mask plane is altered, is inhibited (Figures 5, 6). In alternative arrangements, instead of using triple-ported RAM, the auxiliary port is provided by the use of external multiplexing circuitry. <IMAGE>

Title: Forage harvester
Inventor: NAAKTGEBOREN ADRIANUS
IPC: A01F29/10
Filed: 1997-03-27
Abstract: A forage harvester is provided with a front unit, comprising a rotatable cutterhead (36) to which crop material is fed by feeding apparatus comprising stationary lower feedrolls (26, 27) and movable upper feedrolls (20, 21). The upper feedrolls are suspended from the feeder frame (18) by means of a pair of belts (77), which define the lowermost position of the movable feedrolls (20, 21), when no or very little crop is introduced into the harvester. Inevitable accumulation of crop material or dirt on the components of the feeding apparatus will not influence the position to which the feedrolls (20, 21) may be lowered. A steady and even flow of crop material to the cutterhead (36) can hence be maintained, even when little material is introduced.
